    29 In general one can distinguish between '''remote desktop''' and '''remote window''' solutions.\\
    30 While remote desktop solutions present a whole desktop environment (on JURECA we run XFCE) in a single window on the user´s workstation, remote window solutions make applications running on JURECA appear on the local desktop as normal windows managed by the local window manager.
     29In general one can distinguish between '''full desktop mode''' and '''seamless window mode''' solutions.\\
     30While using a full desktop mode presents a complete desktop environment (on JURECA we run XFCE) in a single window on the user´s workstation, the seamless window mode makes applications running on JURECA appear on the local desktop as normal windows managed by the local window manager.

    32 The full-blown and one-click solution for remote visualization providing a remote desktop on frontend nodes and compute nodes is provided using '''Virtual Network Computing (VNC)''' over the login tool '''Strudel'''.
    33 We recomment to use VNC + Strudel as our first choice as it is integrated into our batch system at the moment most efficiently.
    34 For access to remote windows we recomment '''X Persistent Remote Applications (Xpra)''' as a light-weight solution.
